I think, you should log delete transaction and send them to the central location.

>I have an app wherein the user wants to synchronize data from different sources into one cummulative database. The app is in FPD25 and it allows for multi companies. I have suggested the user to create temp companies on the Accounts machine for the data which he brings from other sources ie. Factory and Admin office and then run the update utility I am creating from those companies.
